Explanation:
Water can be purified from through...
Filtration - This involves the use of filter paper to remove solid objects found in water.
Boiling - This involves keeping water at 100 deg celcius for a while through application of heat and this kills microorganisms in the water.
Addition of alum - Alum causes very fine and small particles that are suspending in water to stick together making them large enough to be removed through filtration.
Chemicals used in water treatment...
Chlorine - Chlorine is used to kill bacteria, viruses and other disease causing pathogens found in water
That's all I know...
an atom because its the smallest thing in the entire world and in all orgnaisms
Given:
n = 12 moles of oxygen
T = 273 K, temperature
p = 75 kPa, pressure
Use the ideal gas law, given by
where
V = volume
R = 8.3145 J/(mol-K), the gas constant
Therefore,
Answer: 0.363 m³
The reaction is not at equilibrium and it is in the forward direction.
a.
Given,
[N₂] = 0.910 mol / L
[H₂] = 0.3 mol / L
[NH₃] = 0.0081 mol / L
K = 9.83 x 10⁻²
The balanced chemical equation for the given reaction is,
N₂(g) + 3H₂(g) ⇄ 2NH₃(g)
The formula of equilibrium constant is given by,
K = [NH₃]² / [N₂] [H₂]²
9.83 x 10⁻² = [(0.0081)² ]/ [0.910 × (0.3)²]
⇒9.83 x 10⁻² = (0.00006561) / (0.0819)
⇒9.83 x 10⁻² = 0.0008010989
⇒0.00983 = 0.0008010989
LHS ≠ RHS
Hence, the reaction is not at equilibrium.
b.
The reaction is in forward direction.

Explanation:
when an acid reacts with base and they cancel out defects of each other and as a product salt and water are produced this reaction is called a neutralization process
